Hi Simon, Magnus,
The Renesas Salvator-XS (Salvator-X 2nd version) development board can
be equipped with either an R-Car H3 ES2.0 or M3-W ES1.x SiP, which are
pin-compatible.
This patch series adds initial support for the Renesas Salvator-XS
development board equipped with an R-Car H3 ES2.0 SiP. The support
level is similar to the existing support for Salvator-X with the same
SiP. See below for exceptions.
The Salvator-XS board is similar but not identical to the already
supported Salvator-X board. To avoid duplication, the common parts are
extracted first into its own .dtsi file.
Noteworthy differences are:
- The main clock crystal ticks at a slightly different rate.
- On R-Car H3 ES2.0, SATA no longer uses dedicated pins, but shares
them with the second PCIe channel. To cater for this, a MAX4888B
multiplexer has been added to Salvator-XS. As the default hardware
configuration enables PCIe, I disabled SATA.
- The Versaclock5 clock generator has been replaced by a similar
member of the Versaclock6 family. As the latter is not supported by
Linux yet, I left it out.
- The USB3.0 micro-B connector is replaced by a USB2.0 micro-AB
connector (both are not yet supported, so no change is needed now).
Dependencies:
- renesas-devel-20170608-v4.12-rc4,
- "arm64: dts: salvator-x: Add missing index to PWM pinctrl subnode
name".
For your convenience, I've pushed this series, its dependencies, and a
few related driver changes to the topic/r8a7795-salvator-xs branch of
the git repository at
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git
This has been tested on Salvator-XS with R-Car H3 ES2.0, and Salvator-X
with R-Car H3 ES1.0.
Thanks!
